Definitions
- the invention relates to a method for supplying hydrogen-operated internal combustion engines with oxygen, an inert gas, preferably argon, also being circulated.
- the invention is based on the objective of using inexpensive internal combustion engines for local energy production or for driving machines and vehicles, while avoiding any CO 2 emissions by using hydrogen as a fuel and at the same time noticeably increasing the efficiency of energy conversion.
- Oxygen Storage Material based on complex mixed oxides are able to selectively and reversibly build oxygen into and out of the crystal lattice of the solid phase at medium to high temperatures depending on the oxygen partial pressure and temperature change (DE 102005034071 B4). Accordingly, both temperature changes and changes in the oxygen partial pressure can be used for oxygen enrichment in gases.
- the targeted change in the oxygen partial pressure is also partially implemented by flushing gases such as CO2 or steam (EP 0913 184 B1) or chemical reactions such as the partial oxidation of hydrocarbons are carried out on the oxygen storage material (US 6379586 B1). So far, there is no reliable information on the energy requirements of the process.
- a hydrogen cycle engine requires pure oxygen, since all the gaseous impurities that have entered accumulate more and more during operation and lead to an increase in the amount of gas recirculated or the total pressure in the gas cycle. Therefore, the excess amount of gas would have to be blown off from time to time, but the inert gas circulated would also be lost. This would have to be topped up regularly and z. B. in vehicles can also be carried in a pressure tank. This is not practical. In addition, atmospheric nitrogen brought in with the oxygen would lead to the formation of nitrogen oxides and, under certain circumstances, form nitrous acid or nitric acid with the condensation water.
- a hydrogen cycle engine must be designed as a gas-tight engine and operated with a nitrogen-free oxidizer gas.
- the invention is based on the object of realizing an inexpensive, local supply of pure oxygen for a hydrogen cycle engine with an argon cycle by separating it from the ambient air without having to use the useful work output of the engine.
- the object is achieved in that OSM ceramics as well as the exhaust gas heat and the low oxygen partial pressure of the exhaust gas are used to generate oxygen.
- At least two reactors filled with OSM ceramics are used, which are alternately flushed with exhaust gas and regenerated with air. Loss of inert gas and the introduction of atmospheric nitrogen are avoided by intermediate flushing with low-pressure steam. The latter is generated with the waste heat of the exhaust gas or the exhaust air.
- the reactors are flushed, a mixture of water vapor, inert gas and oxygen is produced. Subsequently, the oxygen content in the gas phase is noticeably increased by the condensation of the water vapor.
- the cycle gas is therefore to be equated with the oxidizer gas after the H20 separation.
- the process must be run in such a way that only the amount of oxygen required for combustion is released. However, excess oxygen does not interfere too much, it would also be circulated and thereby slows down the oxygen release of the OSM.
- the oxygen content in the circulating gas is set by varying the flushing time of the respective OSM reactor with the circulating gas.
- a bypass valve is used for this, which by bridging the OSM reactors enables the flushing time of the OSM reactors with the circulating gas to be varied freely. It is advantageous here that a regeneration time that deviates from the flushing time with circulating gas can be used for the regeneration of the OSM reactors with air. This ensures that the OSM ceramic is always adequately loaded with oxygen.
- the method for supplying oxygen to a hydrogen cycle engine 1 with 100 kW fuel output is shown schematically in FIG. 1.
- the exhaust gas from the hydrogen cycle engine 1 is fed directly via a switching valve 2 to a first reactor 4 which is filled with an OSM ceramic.
- a mixed oxide with the composition Cao, 5Sro, 5Feo, 5Mno, s03-ö, which was synthesized from the individual oxides or carbonates by solid-state reaction, is used as the OSM ceramic. It was mixed with 25% by volume of an organic burn-out material, plasticized with the addition of organic binders and thickening agents and extruded into thin rods with a diameter of approx. 2 mm. The extrudates are sintered at 1,420 ° C.
- the circulating gas enriched with the oxygen in the first reactor 4 is passed through the further switching valve 3 and from this via an outgoing manifold for circulating gas 6 through a first heat exchanger 15 of a low-pressure steam generator 8, in which part of the exhaust gas heat is used to generate steam ( ⁇ 110 ° C , ⁇ 0.5 bar) is used.
- the low-pressure steam generator 8 can also be heated via a separate, further heat exchanger 16 with the oxygen-depleted exhaust air, which is alternately routed from the second reactor 5 or from the first reactor 4 via the collecting line for exhaust air 7.
- the gas mixture of the manifold for cycle gas 6 of water vapor, argon and oxygen is after Passing through the first heat exchanger 15 of the low-pressure steam generator 8 subsequently passed through an air-cooled condenser 9, so that the water vapor is condensed out.
- the liquid water is introduced into the liquid phase of the low-pressure steam generator 8, with excess water that has accumulated being drained off via an overflow.
- the cycle gas consisting of argon and oxygen is temporarily stored in a membrane gas reservoir 12 at approximately ambient pressure and is fed back to the hydrogen cycle engine 1 from there.
- the membrane gas reservoir 12 is used for better homogenization of the circulating gas, since fluctuating oxygen contents can occur in this.
- the oxygen partial pressure in the membrane gas reservoir 12 is constantly monitored with an oxygen sensor 14 and driven to the preset target value by increasing the purging time in the first reactor 4 and / or second reactor 5 with circulating gas if the oxygen content is too low, if the oxygen content is too high however, is lowered.
- the membrane gas storage 12 also serves to restart the system after it has come to a standstill without an external gas supply.
- the second reactor 5 or first reactor 4 which is in the regeneration cycle with air, is flushed with low-pressure steam at the end of the cycle via a valve for fresh air 11, which is connected on the inlet side to the low-pressure steam generator 8, in order to remove the remaining air from the second reactor 5 or first reactor 4 into the collecting line for exhaust air 7 so that no foreign gases or residual air remain in the second reactor 5 or first reactor 4 and subsequently get into the circulating gas.
- both switching valves 2 and 3 switch simultaneously, as a result of which the supply of the circulating gas is diverted from the first reactor 4 to the second reactor 5 or from the second reactor 5 to the first reactor 4 and at the same time the air is supplied from the second reactor 5 to the first reactor 4 or from the first reactor 4 to the second reactor 5.
- the oxygen content in the cycle gas is set in a simple manner by varying the flushing time of the first reactor 4 or of the second reactor 5 with the cycle gas.
- This purpose is served by a bypass valve 13 which enables the flushing time of the first reactor 4 or of the second reactor 5 with the circulating gas to be varied freely. It is advantageous here that for the regeneration of the second reactor 5 or the first reactor 4 with air, a regeneration time that deviates from the flushing time with circulating gas can be used. This ensures that the OSM ceramic is adequately loaded with oxygen.
